yes that's it!!! Thanks so much an have a nice weekend!

<expt>
/ subjects = (1 of 2)
/ blocks = [1 = sessie; 2= practice; 3 = test; 4 = vas]
/ postinstructions = (End)
</expt>

makes no sense if there is no 2nd <expt> element in the respective script. Delete the /subjects attribute entirely then.

Ok, thanks!  So this is my file that should lead to the 2 different experiments:
<batch >
/ file = "training.exp"
/ subjects = (1 of 2)
/ groupassignment = subjectnumber
</batch>

<batch >
/ file = "control.exp"
/ subjects = (2 of 2)
/ groupassignment = subjectnumber
</batch>



And this is how my current <exp> element looks like in both the separate inquisit files:

<expt>
/ subjects = (1 of 2)
/ blocks = [1 = sessie; 2= practice; 3 = test; 4 = vas]
/ postinstructions = (End)
</expt>

No, those are unrelated problems. One step at a time: Attach the files and I can tell you what's wrong.

As for the <expt> elements: You write them as always. The question you need to ask yourself: How many between-subjects conditions are there in your "training" and your "control" script respectively? Then think about which numbers you feed into each via the <batch>. As discussed earlier, "training.exp" only gets odd ids (1,3,5,...), "control.exp" only gets even ids (2,4,6,...). The <expt> elements in those scripts need to account for that.

That was my first thought too, but the file names are quite simple and are correct. However, currently  I am not referring to the batch in the scripts of the separate experiments as I am not clear how to write the <exp> elements, so i assume that is the problem?

If Inquisit tells you it can't find the file(s), you can be 99.9999% certain that there is an error somewhere in your syntax (a subtle typo, etc.). Check those thoroughly.

Hi Dave,

Sorry to bother you again, but I have tried different things and I still have had no luck in getting the experiment to run.

When trying to run the batch file, I get the following comment: "File not found. Please verify that the file name path is correct."
However, the file path is correct, the only thing I am not sure of is the <exp> elements that you mentioned in your last post. I could not find it in the tutorials, but how should that look like?

Thanks again!!!

groupnumbers don't exist in Inquisit 3, so yes, that's an issue.

With

<batch>
/ file = "training.exp"
/ subjects = (1 of 2)
/ groupassignment = subjectnumber
</batch>

<batch>
/ file = "control.exp"
/ subjects = (2 of 2)
/ groupassignment = subjectnumber
</batch>                               

what you're doing is assigning *odd* subjecnumbers to "training.exp" and *even* subjectnumbers to "control.exp". You must thus make sure that "training.exp" can deal with *odd* numbers -- as per its <expt> etc. element(s) -- and "control.exp" has things set up to deal with *even* ids. If you have no applicable condition defined, you'll get a blank screen / nothing.

Well I tried the same as you proposed, but with the correct file names: (I just noticed i posted this wrong, i am working on inquisit 3, could that explain the problem?)

<batch>
/ file = "training.exp"
/ subjects = (1 of 2)
/ groupassignment = groupnumber
</batch>


<batch>
/ file = "control.exp"
/ subjects = (2 of 2)
/ groupassignment = groupnumber
</batch>

Impossible to answer without the code / launch page.
